Empty tcpdump - ash - 04-17-2014 01:09 AM

Hi,

On some agents of my WPT private instance i got empty results of network packet trace. I tried to investigate this problem but cannot figure out any reason. Wireshark captures packets properly.

Any ideas?

Finally I managed to identify the reason of this. Be patient if you have two network adapters. I use old laptops as agent machines and often they are connected to LAN by wire but still have enabled but not active wireless adapter. Best practice is to disable all unnecessary network adapters. Since I did it I no longer have any problems with capturing network packets.
